Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609324, here are decompositions:

101 + 31609223 = 31609324
233 + 31609091 = 31609324
293 + 31609031 = 31609324
353 + 31608971 = 31609324
431 + 31608893 = 31609324
503 + 31608821 = 31609324
587 + 31608737 = 31609324
797 + 31608527 = 31609324

Showing the first eight; more decompositions exist.
